Growth hormone secretagogues

ABSTRACT

This invention relates to novel compounds which are useful in the modulation of endogenous growth hormone levels in a mammal. The invention further relates to novel intermediates for use in the synthesis of said compounds, as well as novel processes employed in these syntheses. Also included are methods of treating a mammal which include the administration of said compounds.

Growth hormone, which is secreted by the pituitary gland, has wide-ranging developmental effects on the organism. Artificial manipulation of growth hormone levels has been demonstrated to have significant therapeutic utility. Human growth hormone supplementation has been shown to be an effective treatment for growth hormone deficiencies and their related disease states in humans. Apart from this application, studies have uncovered new and significant properties of growth hormone which lend further importance to the ability to control growth hormone levels. For example, clinical studies have indicated that growth hormone supplementation may be useful in combating the maladies of ageing in humans. Elevated growth hormone levels in animals have been shown to result in increased lean muscle mass. One application of this latter observation could result in higher production of leaner meat products or in the production of larger and/or stronger animals.

While growth hormone is naturally produced by the pituitary gland, the secretion of growth hormone into the bloodstream is controlled by a second protein, Growth

Hormone Releasing Factor (GRF). This hormone is also commonly known in the art as somatocrinin, Growth Hormone Releasing Hormone (GHRH), and Growth Releasing Hormone (GRH).

There are two ways to approach the problem of increasing circulating levels of growth hormone: (1) increase the level of human growth hormone in the organism directly or (2) increase the organism's natural tendency to produce growth hormone. The latter strategy may be achieved via supplementation with GRF. GRF has been demonstrated to increase the circulatory levels of growth hormone in vivo. (Rivier, et al., Nature (London), 300:276 (1982). The effect of GRF, including structural analogs thereof, on growth hormone production has been-widely studied. A primary obstacle to the use of GRF as a direct supplement is its short lifespan in vivo. L. A. Frohman, et al., Journal of Clinical Investigation, 78:906 (1986). More potent and/or longer lasting GRF molecules are therefore desirable for the development of effective human therapeutic or animal husbandry agents.

The structure of GRF has been modified in numerous ways resulting in longer lasting and/or more potent GRF analogs. It has been demonstrated that the first 29 amino acids from the N-terminus are sufficient to retain full GRF activity. Speiss, et al., Biochemistry, 21:6037 (1982). One strategy has been the incorporation of novel D-amino acid residues in various regions of the GRF molecule. V. A. Lance; et al., Biochemical and Biophysical Research Communications, 119:265 (1984); D. H. Coy, et al., Peptides, 8(suppl. 1):49 (1986). Another strategy has modified the peptide backbone of GRF by the incorporation of peptide bond isosteres in the N-terminal region. D. Tourwe, Janssen. Chim. Acta, 3:3 (1985); S. J. Hocart, et al., Journal of Medicinal Chemistry, 33:1954-58 (1990). A series of very active analogs of GHRH is described in European Patent Publication 511,003, published Oct. 28, 1992.

In addition to the actions of GHRH there are various ways known to release growth hormone. For example, chemicals such as arginine, L-3,4-dihydroxyphenylalanine (L-DOPA), glucagon, vasopressin, and insulin-induced hypoglycemia, as well as activities such as sleep and exercise, indirectly cause growth hormone to be released from the pituitary by acting in some fashion on the hypothalamus, perhaps either to decrease somatostatin secretion or to increase the secretion of GHRH.

In cases where increased levels of growth hormone are desired, the problem has generally been solved by providing exogenous growth hormone or by administering GHRH, or a related peptidyl compound which stimulates growth hormone production or release. In either instance the peptidyl nature of the compound has necessitated that it be administered by injection.

Other compounds have been developed which stimulate the release of endogenous growth hormone, such as analogous peptidyl compounds related to GHRH. These peptides, while considerably smaller than growth hormones are still susceptible to metabolic instability.

Administration of the hexapeptide growth hormone releasing peptide-6 (GHRP-6) results in the secretion of growth hormone in many species, including humans. This peptide is one of a series of synthetic peptides, the structures of which were based on the pentapeptide Met-enkephalin. It has been shown that GHRP binds specifically to the pituitary, although the binding does not involve the opioid, GHRH, or the somatostatin receptors.

In recent years significant efforts have been taken to develop nonpeptidyl analogs of this series of compounds. Such compounds, termed growth hormone secretagogues, should be orally bioavailable, induce the production or release of growth hormone, and act in concert, or synergistically with GHRH. These compounds are non-peptidyl in nature and are, therefore, more metabolically stable than growth hormone, growth hormone releasing hormone, or analogs of either of these proteins.

The compounds of this invention are especially desired due to the enhanced in vivo pharmaceutical activity of the compounds.

The compounds of the present invention may be prepared by a number of routes, many of which are known to those of skill in the art. The particular order of steps to be employed in the synthesis of compounds of formula I is dependent upon the compound to be synthesized, the starting material employed, and the relative lability of the various substituted moieties.

During any of the following synthetic sequences it may be necessary or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by employing conventional protecting groups as described, supra.

The compounds used in the method of the present invention may have one or more asymmetric centers. As a consequence of these chiral centers, the compounds of the present invention occur as racemates, mixtures of enantiomers and as individual enantiomers, as well as diastereomers and mixtures of diastereomers. All asymmetric forms, individual isomers and combinations thereof, are within the scope of the present invention.

The terms “R” and “S” are used herein as commonly used in organic chemistry to denote specific configuration of a chiral center. The term “R” (rectus) refers to that configuration of a chiral center with a clockwise relationship of group priorities (highest to second lowest) when viewed along the bond toward the lowest priority group. The term “S” (sinister) refers to that configuration of a chiral center with a counterclockwise relationship of group priorities (highest to second lowest) when viewed along the bond toward the lowest priority group. The priority of groups is based upon their atomic number (in order of decreasing atomic number). A partial list of priorities and a discussion of stereochemistry is contained in Nomenclature of Organic Compounds: Principles and Practice, (J. H. Fletcher, et al., eds., 1974) at pages 103-120.

In addition to the (R)-(S) system, the older D-L system is also used in this document to denote absolute configuration, especially with reference to amino acids. In this system, a Fischer projection formula is oriented so that the number 1 carbon of the main chain is at the top. The prefix “D” is used to represent the absolute configuration of the isomer in which the functional (determining) group is on the right side of the carbon atom at the chiral center and “L”, that of the isomer in which it is on the left.

In order to preferentially prepare one optical isomer over its enantiomer, a number of routes are available. As an example, a mixture of enantiomers may be prepared, and then the two enantiomers may be separated. A commonly employed method for the resolution of the racemic mixture (or mixture of enantiomers) into the individual enantiomers is to first convert the enantiomers to diastereomers by way of forming a salt with an optically active acid or base. These diastereomers may then be separated using differential solubility, fractional crystallization, chromatography, or the like. Further details regarding resolution of enantiomeric mixtures may be found in J. Jacques, et al., Enantiomers, Racemates, and Resolutions, (1991).

Representative starting material for this synthesis is a compound of formula Va, which may be reacted with an ethinylamine of formula VI, with R6 and R7 as defined in Formula I, by methods known in the art to yield a compound of formula VII. Alternatively, a compound of formula Vb may be coupled with a compound of formula VI using activating agents for N-acylation reactions known in the art, like HOBT, DCC, EDC, oxalyl chloride, TBTU or other coupling reagents known to the skilled artisan, to result in a compound of formula VII. Preferred for the practice of the present invention is TBTU. Intermediates of formula Vb and VI are commercially available or can be prepared by methods known in the art. Intermediates of formula Va may be prepared from commercial compounds by standard methods as described in Tetrahedron Lett. 25 (1984), 4553-4556.

A compound of formula VII may be hydrated by standard methods to yield a compound of formula VIII and subsequently cyclized by treatment with a deprotonating agent, such as sodium hydride, optionally in the presence of an alkylating agent to yield a compound of formula IX. Treatment of the resulting compound with a bromination reagent, such as N-bromosuccinimide, results in a compound of formula X. Reaction with an amine generates compounds of formula XI. Representative reactions are provided in Scheme A below. An example of formula IX where Q is SO₂, R8 is hydrogen and R9 is 4-chlorophenyl is described in Pestic. Sci. 39 (1993), 185-192.

Scheme B shows an alternative synthesis for acetyl intermediates of Formula VIII:

Esters of aminoacids of Formula VI a, preferably methyl or ethyl esters, are coupled with derivatives of carboxylic acids or sulfonic acids of Formula V (with R20 meaning OH or Cl, respectively) by methods described in Scheme A to give intermediates of Formula VIIa. The esters are hydrolized by standard methods to give carboxylic acids of Formula VIIb. These are treated with organometallic methyl compounds to prepare the acetyl intermediates of Formula VIII. Preferred organometallic reagents are methyl Grignard reagents (M=MgCl, MgBr, or MgI) or methyl lithium (M=Li), more preferred is methyl lithium. Examples for this reaction are known from the literature, e.g. J. Org. Chem. 58 (1993), 4758; J. Org. Chem. 62 (1997), 6862; Tetrahedron Lett. 35 (1994), 3745. In a preferred method a solution of the carboxylic acid in a solvent like THF or DME is treated with an excess of methyl lithium in diethylether at a temperature below −60° C. followed by warming to room temperature.

Compounds of Formula I in which m=2 may be prepared as shown in Scheme C below.

A compound of formula XII is obtained by treatment of a protected methylamine with a deprotonating agent like butyllithium as described for example in Tetrahedron Lett. 35(24), 1994, 4067-70. The substituent “PG” means a protecting group, which is known to the artisan, and all other substituents are as defined by Formula I, herein. One preferred protecting group is the BOC group or another N-protecting group known in the art and stable under the reaction conditions. A compound of formula X is treated with a compound of formula XII to yield a compound of formula XIa.

It is to be understood that the bromine group on the compound of formula X may in fact be any suitable leaving group, as defined herein.

The term “leaving group” refers to a group of atoms that is displaced from a carbon atom by the attack of a nucleophile in a nucleophilic substitution reaction. Suitable leaving groups include bromo, chloro, and iodo, benzenesulfonyloxy, methanesulfonyloxy, and toluenesulfonyloxy. The term “leaving group” includes activating groups as defined above.

A second portion of the overall synthesis of compounds of formula I is provided in Scheme D below.

Representative starting material for this synthesis is a compound of formula XIIIa, which may be a chemically-protected derivative of the amino acid serine. By chemically-protected it is meant that both the amino- and carboxy-functional groups have been suitably protected in order to facilitate further reactions with this molecule. Such protection reactions are known to those of skill in the art, and may be applied to other suitable starting materials. Intermediates of formula XIIIa are commercially available, or may be prepared by standard syntheses of amino acids. Such syntheses are well known to persons of ordinary skill in the art and are described, for example, in Chemistry and Biochemistry of Amino Acids, (G. C. Chapman ed., 1985). The protected amino group may be specifically deprotected, e.g. if PG is a Boc group, using trifluoroacetic acid and methylene chloride, to allow for further reactions with this amino functional group. This deprotection reaction results in a compound of formula XIIIb.

A compound of formula XIIIb may then be N-acylated with an amino-protected compound of formula XIV for instance HOOC—C₁-C₆alkylNHR10 or HOOC— (substituted C₁-C₆alkyl)NHR10 or HOOC-(unsubstituted or substituted C₃-C₈ cycloalkyl)NHR10, wherein R10 is an amino protecting group (PG), to produce a compound of formula XIIIc.

Compounds of formula XIV are commercially available, or are readily prepared from suitable available starting materials. The protected carboxy group on the compound of formula XIIIc is then selectively deprotected, typically using lithium hydroxide, to generate a compound of formula XIII. A compound of formula XIII is then coupled with a compound of formula XI and subsequently deprotected to generate a compound of formula Ia.

Representative reactions are provided below in Scheme D.

An alternative synthesis for compounds of formula Ia is shshown in Scheme E below:

A compound of formula XIIIa, as defined for Scheme D, is selectively deprotected, typically using lithium hydroxide, to generate a compound of formula XIIId, which may then be employed to N-acylate a compound of formula XI, generating a compound of formula XV. Subsequent deprotection results in a compound of formula XVa. A compound of formula XVa is then coupled with a compound of formula XIV, as defined for Scheme D, and subsequently deprotected to generate a compound of formula I.

Suitable activating agents for the N-acylation reactions in Scheme D and Scheme E are known in the art and include DCC, HOBT, EDC, and oxalyl chloride. Preferred for the practice of the present invention are HOBT or TBTU.

Compounds of formula XIII in which the starting material XIIIa is optionally substituted 2-Nboc-amino-5-arylpentanoic acid methyl ester, optionally substituted 2-Nboc-amino-4-arylbutanoic acid methyl ester or 2-Nboc-amino-3-(3-indolyl)-propionic acid methyl ester may also be prepared by the routes described in Scheme D and Scheme E.

Compounds of formula XIb may also be employed in the reactions described in Scheme D and Scheme E.

R1, R2, R3, R4, R5, R6, R7, R8, R9 and Q in Schemes A through E are as defined for Formula I.

The preferred reaction temperature range employed in these reactions is between −40 and 150° C., and the most preferred range is between 10 and 40° C. These reactions may be conveniently carried out in situ, without isolation of the particular compound after its preparation.

The compounds of the present invention can be useful for modulating growth hormone secretion and as research tools.

Compounds of formula I possess growth hormone secretagogue activity. Growth hormone secretagogue activity can be determined using a typical assay which may employ pituitary cells established in culture, followed by a challenge with the various compounds of formula I, and the levels of growth hormone determined accordingly. Growth hormone levels may be calculated using various radioimmunoassay techniques known to those of skill in the art. One example of such an assay is detailed herein.

Thus compounds of formula I find use in the treatment of physiological conditions which are modulated or ameliorated by an increase in endogenous growth hormone. In particular the compounds of formula I are useful in the treatment of conditions or diseases which cause or are mediated by growth hormone deficiencies and maladies associated with ageing in humans. The compounds of formula I are hence useful in the treatment of osteoporosis, physiological short stature including growth hormone deficient children and short stature associated with chronic illness, growth retardation associated with the Prader-Willi syndrome, intrauterine growth retardation, pulmonary dysfunction and ventilator dependency, insulin resistance, cachexia and protein loss due to chronic illness such as cancer or AIDS, as well as congestive heart failure. The compounds of formula I also hence find use in improving muscle strength and mobility, metabolic homeostasis, renal homeostasis especially in the elderly, accelerating the recovery of patients having undergone trauma especially major surgery, improving a negative energy balance in a patient, accelerating bone fracture repair, preventing catabolic side effects associated with therapy, the attenuation of protein catabolic responses following major surgery, the acceleration of wound healing and the treatment of immunosupressed patients. In this connection, compounds of formula I also find use in the manufacture of a medicament for the treatment of the human or animal body by therapy, in particular the therapeutic treatment of conditions or diseases which cause or are mediated by growth hormone deficiencies maladies associated with ageing in humans. In particular compounds of formula I also find use in the manufacture of a medicament for any of the specific uses indicated above.

The compounds of formula I also find use in a method of increasing endogenous levels of growth hormone in mammals and in particular humans and farm or companion animals. Thus the compounds of formula I find use in a method of promoting growth, in particular, increasing lean muscle mass, in an animal, in particular an animal farmed for food including cow, sheep, pig and chicken. The compounds also find particular use in the treatment of disorders of ageing in companion animals.

The invention further encompasses methods employing the pharmaceutically acceptable salts of the compounds defined by formula I. Although generally neutral, a compound of this invention can possess a sufficiently acidic, a sufficiently basic, or both functional groups, and accordingly react with any of a number of inorganic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt.

The term “pharmaceutically acceptable salt” as used herein refers to salts of the compounds of formula I which are substantially non-toxic to living organisms. Typical pharmaceutically acceptable salts include those salts prepared by reaction of the compounds of the present invention with a pharmaceutically acceptable mineral or organic acid or an inorganic base. Such salts are known as acid addition and base addition salts.

Acids commonly employed to form acid addition salts are inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, and the like, and organic acids such as p-toluenesulfonic, methanesulfonic acid, oxalic acid, p-bromophenylsulfonic acid, carbonic acid, succinic acid, citric acid, benzoic acid, acetic acid, and the like. Examples of such pharmaceutically acceptable salts are the sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, acetate, propionate, decanoate, caprylate, acrylate, formate, isobutyrate, caproate, heptanoate, propiolate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, butyne-1,4-dioate, hexyne-1,6-dioate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, hydroxybenzoate, methoxybenzoate, phthalate, sulfonate, xylenesulfonate, phenylacetate, phenylpropionate, phenylbutyrate, citrate, lactate, γ-hydroxybutyrate, glycollate, tartrate, methanesulfonate, propanesulfonate, naphthalene-1-sulfonate, naphthalene-2-sulfonate, mandelate, mesylate, and the like. Preferred pharmaceutically acceptable acid addition salts are those formed with mineral acids such as hydrochloric acid and hydrobromic acid, and those formed with organic acids such as maleic acid and methanesulfonic acid.

Salts of amine groups may also comprise quaternary ammonium salts in which the amino nitrogen carries a suitable organic group such as an alkyl, alkenyl, alkynyl, or aralkyl moiety.

Base addition salts include those derived from inorganic bases, such as ammonium or alkali or alkaline earth metal hydroxides, carbonates, bicarbonates, and the like. Such bases useful in preparing the salts of this invention thus include sodium hydroxide, potassium hydroxide, ammonium hydroxide, potassium carbonate, sodium carbonate, sodium bicarbonate, potassium bicarbonate, calcium hydroxide, calcium carbonate, and the like. The potassium and sodium salt forms are particularly preferred.

It should be recognized that the particular counterion forming a part of any salt of this invention is not of a critical nature, so long as the salt as a whole is pharmacologically acceptable and as long as the counterion does not contribute undesired qualities to the salt as a whole.

This invention further encompasses methods employing pharmaceutically acceptable solvates of the compounds of Formula I. Many of the formula I compounds can combine with solvents such as water, methanol, and ethanol to form pharmaceutically acceptable solvates such as the corresponding hydrate, methanolate, and ethanolate.

This invention also encompasses methods employing the pharmaceutically acceptable prodrugs of the compounds of formula I. A prodrug is a drug which has been chemically modified and may be biologically inactive at its site of action, but which may be degraded or modified by one or more enzymatic or other in vivo processes to the parent bioactive form. This prodrug should have a different pharmacokinetic profile than the parent, enabling easier absorption across the mucosal epithelium, better salt formation or solubility, or improved systemic stability (an increase in plasma half-life, for example).

Typically, such chemical modifications include:

1) ester or amide derivatives which may be cleaved by esterases or lipases;

2) peptides which may be recognized by specific or nonspecific proteases; or

3) derivatives that accumulate at a site of action through membrane selection of a prodrug form or a modified prodrug form; or any combination of 1 to 3, supra. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in H, Bundgaard, Design of Prodrugs, (1985).

As used herein, the term “effective amount” means an amount of compound of the instant invention which is capable of inhibiting, alleviating, ameliorating, treating, or preventing further symptoms in mammals, including humans, which may be due to decreased levels of endogenous growth hormone.

By “pharmaceutically acceptable formulation” it is meant that the carrier, diluent, excipients and salt must be compatible with the active ingredient (a compound of formula I) of the formulation, and not be deleterious to the recipient thereof. Pharmaceutical formulations can be prepared by procedures known in the art. For example, the compounds of this invention can be formulated with common excipients, diluents, or carriers, and formed into tablets, capsules, and the like. Examples of excipients, diluents, and carriers that are suitable for such formulations include the following: fillers and extenders such as starch, sugars, mannitol, and silicic derivatives; binding agents such as carboxymethyl cellulose and other cellulose derivatives, alginates, gelatin, and polyvinyl pyrrolidone; moisturizing agents such as glycerol; disintegrating agents such as agar agar, calcium carbonate, and sodium bicarbonate; agents for retarding dissolution such as paraffin; resorption accelerators such as quaternary ammonium compounds; surface active agents such as cetyl alcohol, glycerol monostearate; adsorptive carriers such as kaolin and bentonite; and lubricants such as talc, calcium and magnesium stearate and solid polyethylene glycols. Final pharmaceutical forms may be: pills, tablets, powders, lozenges, syrups, aerosols, saches, cachets, elixirs, suspensions, emulsions, ointments, suppositories, sterile injectable solutions, or sterile packaged powders, and the like, depending on the type of excipient used.

Additionally, the compounds of this invention are well suited to formulation as sustained release dosage forms. The formulations can also be so constituted that they release the active ingredient only or preferably in a particular part of the intestinal tract, possibly over a period of time. Such formulations would involve coatings, envelopes, or protective matrices which may be made from polymeric substances or waxes.

The particular dosage of a compound required to treat, inhibit, or prevent the symptoms and/or disease of congestive heart failure in a mammal, including humans, according to this invention will depend upon the particular disease, symptoms, and severity. Dosage, routes of administration, and frequency of dosing is best decided by the attending physician. Generally, accepted and effective doses will be from 15 mg to 1000 mg, and more typically from 15 mg to 80 mg. Such dosages will be administered to a patient in need of treatment from one to three times each day or as often as needed for efficacy.

In addition, the growth hormone secretagogue compounds as disclosed herein may be administered to a patient in need of treatment in combination with other growth hormone secretagogues known in the art, and/or with a suitable bone anti-resorptive agent or agents for the prevention or treatment of osteoporosis and/or loss of muscle strength. Said suitable bone anti-resorptive agents include selective estrogen receptor modulators, bisphophonates, calcitonin, and hormone replacement therapeutic agents. Additionally, PTH may be administered in combination with said growth hormone secretagogues. Said combination therapy may be administered concomitantly or sequentially.

The compositions are preferably formulated in a unit dosage form, each dosage containing from about 0.01 to about 500 mg, more usually about 0.5 to about 200 mg, of the active ingredient. However, it will be understood that the therapeutic dosage administered will be determined by the physician in the light of the relevant circumstances including the condition to be treated, the choice of compound to be administered and the chosen route of administration, and therefore the above dosage ranges are not intended to limit the scope of the invention in any way. The compounds can be administered by a variety of routes including the oral, rectal, transdermal, subcutaneous, topical, intravenous, intramuscular or intranasal routes. For all indications, a typical daily dose will contain from about 0.01 mg/kg to about 20 mg/kg of the active compound of this invention. Preferred daily doses will be about 0.1 to about 10 mg/kg, ideally about 0.1 to about 5 mg/kg. However, for topical administration a typical dosage is about 1 to about 500 mg compound per cm² of an affected tissue. Preferably, the applied amount of compound will range from about 30 to about 300 mg/cm², more preferably, from about 50 to about 200 mg/cm², and, most preferably, from about 60 to about 100 mg/cm².

Suitable dosing ranges of compounds of formula I include 0.01 mg/kg/day to 60 mg/kg/day. Representative pharmaceutical formulations containing compounds of formula I-IV are provided below.

The formulations which follow are given for purposes of illustration and are not intended to be limiting in any way.

The homogenous mixture is poured into forms made of an inert material to produce a drug-containing diffusion matrix having a thickness of about 2-4 mm. This diffusion matrix is then cut to form individual tablets having the appropriate size.

Another formulation employed in the methods of the present invention employs transdermal delivery devices or patches. Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, for example, U.S. Pat. No. 5,023,252, the disclosure of which is herein incorporated by reference. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.

Frequently, it will be desirable or necessary to introduce the pharmaceutical composition to the brain, either directly or indirectly. Direct techniques usually involve placement of a drug delivery catheter into the host's ventricular system to bypass the blood-brain barrier. One such implantable delivery system, used for the transport of biological factors to specific anatomical regions of the body, is described in U.S. Pat. No. 5,011,472, the disclosure of which is herein incorporated by reference.

Indirect techniques, which are generally preferred, usually involve formulating the compositions to provide for drug latentiation by the conversion of hydrophilic drugs into lipid-soluble drugs or prodrugs. Latentiation is generally achieved through blocking of the hydroxy, carbonyl, sulfate, and primary amine groups present on the drug to render the drug more lipid soluble and amenable to transportation across the blood-brain barrier. Alternatively, the delivery of hydrophilic drugs may be enhanced by intra-arterial infusion of hypertonic solutions which can transiently open the blood-brain barrier.

The following Examples and Preparations are illustrative of the processes employed in the synthesis of the compounds of the present invention. As would be understood by persons skilled in the art, other synthetic schemes may be employed to prepare the compounds of the instant invention.

Pituitary Cell Culture Assay for Growth Hormone (GH) Secretion

Fifteen 250 g male Sprague-Dawley rats are used for each assay. The animals are killed by decapitation and anterior pituitaries are removed and placed into ice cold culture medium. The pituitaries are sectioned in small pieces and enzymatically digested using trypsin (Difco) to weaken connective tissue. Pituitary cells are dispersed by mechanical agitation, collected, pooled and then seeded into 96-well plates (50,000 cells/well). After 5 days of culture, the cells formed as monolayer (70-80% confluent). Cells are then washed with medium (without phenol red) and incubated for 90 min at 37° C. Afterwards the cells are challenged to secrete GH by the addition of GH secretagogues to the medium. After 45 min at room temperature, the medium is removed, filtered and stored frozen until radioimmunoassays for rat GH were performed. Doses of secretagogue are added in triplicates. Compounds disclosed herein are active in the assay as described. The compounds cause a stimulation of GH secretion resulting in at least 20% increase of the basal level of GH with and EC50<500 nM. Preferred compounds caused a 50% increase with an EC50<50 nM, and more preferred compounds a 50% increase with an EC50<10 nM. Both EC50 and efficacy values were calculated by the 4-parameter logistic equation. Such values were pooled and represented as mean+/−standard error, when appropriate.
